FEATURES OF KINETICS OF DECAY AND FORMATION OF STRUCTURE IN СHROMO-MOLYBDENUM-VANADIUM STEEL AT CONTINUOUS COOLING FROM DIFFERENT TEMPERATURES OF AUSTENITIZATION

open access: yesЛитьë и металлургия, 2016
Influence of austenite grain size of chrome-molybdenum-vanadium steel on formation of structure at continuous cooling has been studied. It is shown, that at the coarsen of grain with increasing temperature of austenitization from 850 till 1050°С ...

Weldability of Austenite Steel

open access: yesMetalurgija, 2004
The paper presents properties of austenitic steels and the influence of single chemical elements and processing parameters on them. A particular attention is paid to the weldability of austenite steels. Weldability procedures are described and a critical review on welding possibility of austenite steels by high frequency procedure is given.

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

open access: yessteel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

open access: yessteel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study explores the impact of surface condition on high‐cycle fatigue performance of a high‐nitrogen martensitic tool steel manufactured through powder metallurgy and hot isostatic pressing. In near‐net manufacturing applications, acid‐leaching pickling treatment and/or machining is used as a post‐treatment to remove the powder container ...

Evaluation of carbon diffusion in heat treatment of H13 tool steel under different atmospheric conditions

open access: yesJournal of Materials Research and Technology, 2015
Although the cost of the heat treatment process is only a minor portion of the total production cost, it is arguably the most important and crucial stage on the determination of material quality.

Accelerated Fatigue Testing of High‐Speed Steel

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The staircase method is commonly employed in the characterization of metals to determine their fatigue limit. In this approach, the stress amplitude is systematically varied around the assumed fatigue limit in consecutive tests. However, its applicability for in‐process optimization in alloy design and development is limited by the large ...
